Question

"He was here a few weeks ago,and he came again yesterday,"she said.(改为间接引语）
给出原因,为什么要这样写?

Answer 1

She said（that）he had been there a few weeks before and that he came again the day before,
第一个that可以省略,第二个that 不能省.过去时was改为had been；
还有间接引语中规定：here改为there ,ago改为before,yesterday 改为the day before.
